To all whom it may concern:

Be it known that I, WALTER a citizen" of. the United States, residing atChicago,'-int-he county of Cook and State of Illinois, haveinventedcertain new and use ful I n 'rovement-s in Release-Rigging, of

he follow-ing'is a specification.

'lhe-ohjectiofmy invention is to produce a joint between thehandoperated lever and the lockinglpin lifting lever of a character thatwill permit the disengagementof the levers for repairs without heatingor spread-' ing' the metal ofkeither lever.

'Theffurtliefohject o'f'my invention is to provide a stop .to preventthe accidental displacement'1 or. disconnection of the levers; and withthese-and minor objects in view, my invention consists of the parts andcomhination ofparts as will be hereinafter more fully pointed out.

In the drawing, A View of the end sill of a' car with" my inventionattached; Fig. 2 is a front elevation ofthe same, and Fig. 3 is an endelevation of the same with the hand operated lever The numeral 1designates the end sill of a car .of any approved construction, to whichthe hand operated lever- 2 is secured by suitable clips. The outer endof'the lever 2 is provided with a hand crank 3 and its inner end with acrank 4, said crank terminat ing in an open hook 5, the free end ofwhich is bent-up to form a stop6, said stop being disposed verticallyand within the lines of said free'endv I have shown the stopas beingcurved on its end face, as

more clearly seen in Fig. 3, as such an out-.

line facilitates the removal of the pin lift ing lever from this hook,as will be hereinafter described.

.- The pin lifting lever 7 is provided with the hook8 at its inner endfor engagement with the eye of thelocking pin of the coupler and isprovided with a closed eye 9 at its outer end, which is at right anglesto ,the'

hook 8.

. To assemble the two levers, the closed eye 9 is placed in a positionat right angles to that shown in Fig. 2 and is passed over the stop 6,then overthe free arm of the hook 5 and thence passed around tothe bodythe crank- 4 to the position shqwn in Figs. 1

and 2, inwlfich position alertness eye 9 is on .the'inainbody of thecranks while the body of the lever 7 rests upon'the free P. MURPHYyFigure 1 is a top arm of the hook 5, as clearly shown in Figs. land 2,said lever 7 being prevented from dtigengagement from the hook 5 by thes p 6.

In Fig. 1, I have shown in dotted lines,

the maximum movements of the pin lever incident to the movement of. thedraw bar carrying the coupler in transit. In one of the dottedpositions, it will be noted that the lever 7 is locked against the stop6, while in'the other position the closed eye 9 is locked on the crank4. In Fig. 2, I have shown a maximum positionin dotted lines of the pinlifting lever, in which position it will be noted th at i t is stillheld from disengagement with the lever 2 by means of the stop 6.

The dotted position shown in Fig. 2 is rather extreme for the pinlifting levelg 'nasmuch.

as all locking pins drop back somewhat. It will be seen that thisconstruction provides for a lever of this character which isnoncollapsible and at the same time will perinit are pin lifting leverto remain in itselevated position after lifting the locking pin and alsopermit the hand operated lever to assume its normal position with theoperating handle 3 depending below the car sill. This is important asthere is no danger of an accident to the operator or damage to thelifting lever when the cars are brought together in the act of coupling.

In the event that the draw bar of one car breaks away from itsfastenings, the pin lifting lever is free to follow it to the extent ofthe position shown by the outermost dotted lines in Fig. 1, but as soonas it reaches this position, the pin lifting lever becomes locked to andrigid with the crank 4: and its hook 5 and further movement is stop ed,which will result in some types of coup ers in the locking pin beingwithdrawn from the coupler and uncouplingsthe cars, thereby preventmgthe draw bar from being pulled entirely from tinder the car and droppingon to the road bed.

In release rigging, it frequently happens that one of the levers becomesdamaged and in order to repair the damaged part, it is necessary to takeoff both of the levers. By my oonstruction, I am enabled to takeoffeither leveri,,.separately without disturbing the other. 'For instance,suppose the pin lifting lever is damaged all that is necessary-,is torelease it from the locking pin,

the open hook 5 and then by turning it at right angles, it can be passedover the stop (3 without removing the hand operated lever 2.

The portion 6 limits the backward movement of the rod 7 which isessential to complete lifting of the lock of the couplers. In practicethe brackets of rod 2 are located as near the bends of the rod-as willallow it to rot-ate freely and all the movement of the coupler ispermitted by placing the hook 8 safely away from the eye of the lookunder all service movements and only'in case the coupler or draftattachments failed and the coupler pulled excessively forward, would thehook 8 come in contact with the coupler lock eye.

I claim- 1. A hand operated lever having a crank at'its inner end and anopen hoot: on said crank, the end of the hook lging parallel to thecrank, the hook and t e end of said crank forming two substantiallyparallel members, a pin lifting lever having an eye to engage one ofsaidmembers, a stop on the other member, spid pin lever overlying saidother member in proximity to said stop.

2. A hand operated lever for release rigging, terminatmg in an open hookat its Gap! 0! ml patent may be obtainedftor .and a stop inner end, thefree end of said hook being bent at an angle to, but in line with thebody of said free end to form a stop in combinat-ion with a pin liftinglever.

3. In a release-rigging, the combination with a locking pin liftinglever having a closed eye at its outer end, of a hand operated leverterminating in a crank at its inner end, an open hook at the end of saidcrank, formed at an angle to, but in line with the ody of the free endof said hook, the closed eye of the pin lever being adapted forengagement with the crank of the hand lever and held in lockedengagement therewith by said stop.

4. In a release rigglng, the combination 'with a locking pin leverhaving an eye at its outer end, of a hand operated lever having aci-ank'atits inner end, an open hook at the end of said crank, a stopformed at an angle to, but in line with the free end of said hook, theeye of the lever engaging the crank of the hand lever while the lever issupported on said hook.
